leem 0.2.1

fixed bugs for P() function:
- Normal distribution
- Student’s t-distribution
- Chi-squared distribution
- F distribution # leem 0.3.0
Bugs fixed in plots, no longer needing to use the tabfreq() function directly;
Test of Hypothesis: th()
- Distributions:
  - Test of Normal: ztest
    - one population
    - two population
    - test of proportion
    - print.leem()
    - alternatives
      - two.sided
      - less
      - greater
  - Test of T-Student: ttest
    - one population
    - two population
    - test of proportion
    - print.leem()
    - alternatives
      - two.sided
      - less
      - greater

leem 1.0.0

Gradient colors of graphics take into account the weight of frequencies
Create 3d plots
- Insert shadows on the bars, giving them a 3d appearance
Insert the details argument in the P function to print the expected and variance values of said distributions
